YORK, N, Y., A CORPORATION OF NEW JERSEY COLORING MATERIAL FOR OLEOMARGARINE, BUTTER, AND THE LIKE No Drawing. Application fil-ed July 6,

The object of my invention is to provide a coloring material for oleomargarine and butter and the like that may be marketed and put up for use in dry form.

Until recently a colored oil 'put up in capsule or bottles has been given to the consumer to be worked into the oleomargarine, usually a capsule, or capsules, containing sulficient amount to color the bulk of, oleomargarine as sold to the customer. There are many objections to the use and handling of the gelatin capsule. Y

in water-proof material, such as celluloid and thus enable the seller of the oleomargarine unit of oleomargarine sold..

to enclose a unit of:color powder inevery In making the coloring powder, I use the customary aniline dyes knownas benzenazo b-naphthylanineandortho-toluenzao-b-naphthylanine, commonly known as AB and DB,

respectively. Vegetable coloring dyes,s uch as Arnotto seed, may also be used. The desired combination of dry colors is dissolved in a suitable volatile solvent, such as acetone,

dichlorethylene, trichloretl ylene, ethyl-ketone, and others. Any solvents that will not leave any odors on evaporation are preferred. The solutions are made in such proportions as will give the desired strength of color which is usually determined by the comparison of orimeter.

The colored liquid solution is added to a quantity of starch or other suitable material, and themixture is thoroughly agitated, the aimbeing to coat the particles of starch'or' other 1925.

material with the solution of color. As soon as this has been accomplished uniformly, the solvent of the color is evaporated by continued agitation and turning over of the mass or other suitable means. This operation may be carried out in a suitable closed container, which may be heated, the solvent driven off, collected, and condensed in a suitable condenser so that it may be used again.

The aim of the operation is to give a dry color coat to the starch granules in such a manner that they will not be matted together,

but that, the form. I

In the act of using the colored powder mass will be in true granular for coloring, the following probably occurs x The coloring matter is held on the outsideand probably the inside surfaces of the starch granules by adhesiononly an'd't-here is no true afiinity between the color material and starch. When the colored material is sprinkled on the oleomargarine or butter, the;

starch having greater aflinity for the water present, will absorb the water, swell, and dislodge the colored matter which is not soluble oil or fat,-hence, it leaires the starch and comin water. The colormaterialhas aflinity for bines with the oil or fat. In other words,the

starch granules will dislodge themselves of the color matter and willnot be visible in the oleomargarine thereafter.

I claim:

1. A dry coloring material for oleomargarine and the like consisting of water soluble granules coated and impregnated with'a dry coloring matter.

2. A dry coloring material for oleomargarine and the like cgnsisting of finely divided water soluble particles coated and impregn'ated with a suitable color. 1 i

3. The method of making a coloring material for oleomargarine and butter which consists in dissolving a dyestuif in a volatile solvent carrier, absorbing the colored solution with porous material and evaporating off the solvent. i

" 4:. The method of making a coloring mate I rial for oleomargarin'e and butter which consists in dissolving a dyestuff in a volatile sol- IOU vent carrier, depositing the dyestuff on p0- rous material and evaporating the solvent.

5. The method of making a coloring material for oleomargarine and butter which consists in dissolving a dyestufi' in a volatile solvent carrier, depositing the dyestulf on finely divided absorbent material and removing the solvent.
